Installation

Nimbreth is free for macOS and Linux. Grab the installer for your platform from the download page or the latest release.

macOS

1. Download the DMG for Apple Silicon.
2. Open it and drag Nimbreth into your Applications folder.
3. Launch Nimbreth from Applications.

The build is signed and notarized, so it opens with no security prompts. Intel Macs are not supported.

Linux

AppImage (any distribution)

Make the file executable and run it:

chmod +x Nimbreth-*.AppImage
./Nimbreth-*.AppImage

On Ubuntu 24.04 and newer the system limits the sandbox AppImages can use. Nimbreth detects this and asks how you want to continue: install the deb (it is not affected), or run without the Chromium sandbox. Details in the FAQ.

Debian and Ubuntu (.deb)

sudo apt install ./nimbreth_*.deb

AppImage and deb are both available for x64 and arm64.

Verify your download

Every asset ships with a .sha256 checksum next to it. After downloading:

sha256sum -c Nimbreth-*.sha256

On macOS, use shasum -a 256 -c instead.

Updates

Nimbreth keeps itself current. On macOS it updates in the background and asks you to restart when a new version is ready. On Linux it tells you when an update is out and links you to the download. See Updating for the details.

Supported platforms

Power users

Nimbreth also ships as a terminal app (CLI and TUI) alongside each release, for scripting and SSH. It is not documented here yet. If you want it, the tarballs sit next to the desktop installers on the releases page.
